Loïc Wisniewski f040327523 Cap fleet cargo capacity by composition (#56)
The fleet hold was unbounded - GameState.fleet_inventory had no
total_capacity, so a lone ship could carry unlimited resources. Capacity
is now data-driven: only vessels declaring the "cargo" capability
contribute their cargo_capacity stat (interceptor: 20; shield vessel and
gas bomber: 0, unarmed transporters are never in the fleet at all).
Fleet.gd recomputes it in the one place composition can change
(spawn_ships/add_ship/store_ship/_on_ship_destroyed), which also covers
the space<->surface scene-swap restore since that goes through
spawn_ships().

Rock.gd and GasVentField.gd (the two "fly over it to collect" pickup
paths) now check what collect_cargo()/collect_gas_cargo() actually
accepted before consuming their source, instead of assuming an
unlimited hold. The HUD's FLEET HOLD caption shows the live total/cap.

Also fixes test_resource_transfer.gd, which pushed more ore through a
2-ship fleet than the new cap allows - it now spawns the largest fleet
every unlocked doctrine permits, since that test is about the transfer
UI rather than the cap itself (test_fleet_cargo_limit.gd owns that).

# Generalizes ResourceCounter/GasCounter/CargoCounter/GasCargoCounter - one
# hardcoded node plus one script per resource, times two scenes - into one
# row per GameState.resource_types() entry, built at _ready(). A new
# resource added to ResourceDefinitions.ORDER/DEFINITIONS gets a HUD row
# with no scene edit and no new script, the same way ResourceBar and
# ResourceTransferList already pick up a new resource automatically.
#
# Layout mirrors what it replaces: a BANKED column (left) and a FLEET HOLD
# column (right), one row per resource, each row a resource glyph plus a
# digit readout. Banked rows are always visible, even at zero (matching
# ResourceCounter/GasCounter today); fleet rows hide at zero, since that
# hold isn't the player's yet (see CargoCounter's own note on why).
